tools lib traceevent, perf tools: Rename traceevent_plugin_* APIs

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "traceevent_". This changes
APIs: traceevent_plugin_list_options, traceevent_plugin_free_options_list,
traceevent_plugin_add_options, traceevent_plugin_remove_options,
traceevent_print_plugins
